INCANDESCENT GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 389,588, dated September 18, 1888.

Application filed January Ill, 1888. Serial No. 261,375. (No model.)

tion of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in incandescent gas-burners.

The object of my invention is to produce a burner which is adapted both l'or natural and artificial gas, and in which the size of the flame can be regulated to the amount of light deslred, and to which filaments of any indezo-strnet-ibicm re are applied, so that the flame will heat the filaments white-hot, and thus cause them to produce a brilliant and. steady light by the consumption of a very small amount of gas.

Figure 1 is a vertical section of a burner which embodies my invention. Fig. 2 is a side elevation of the same.

A represents the tip through which the gas escapes, and B the perforated cylinder into the lower portion of which the gas escapes, as in an ordinary Bunsen burner. The upward flow of t gas causes air to bcintroduced through the openings in the bottom of the cylinder and to mingle with the gas for the purpose of producing an invisible heating-flame. This flame produces no light, but does produce an intense heat for the purpose of heating the filaments. y

The cylindcr'B is internally screwthrcaded go at its upper end for any suitable distance, and

insideof this screw-threaded cylinder is a plug orsupport, D, which is cut away upon its sides and pertorared at its ends, asshown, Z s'o.as' to allow the gas to t" reel y escape upward past it, and which plug serves as a support for the other portions of the burner. Rising from the top of thisplug l) is a screw-threaded rod, F, and placcd down ,over this rod and in connection with the top of the plug is'the inverted 5o cone H, which is clamped in position by means of a sleeve or collar, I, which is screwed upon the rod, as shown in Fig. 1. This cone serves to regulate the size of the opening at the top of the cylinder-B, and thus regulate the sizeof the flame. \Vhen the plug is screwed downward inside of the cylinder, the sides of the cone are brought always in contact with the upperinner edges of the cylinder, and the flame will be adjusted accordingly; but when the plug is raised upward the aperture for the escape of the gas is accordingly enlarged, and the flame is increased in size accordingly. Placed upon the screw-rod and made vertically adjustable thereon is the plate or disk J, which is made separate and independent of the cone, as it must be adjusted either up or down upon the rod at the same time that the cone and plug are adjusted in relation to the top of the cylinder. Upon the outer edge of this disk is placed a sripportingriug, U, which is made independent 01' the disk and to which the filaments 1? are secured. These filaments are of any desired number, length, and thickness and made of any suitable indestructible mz' "crial-- such as platinum, iridium, orzirconia. These filaments become white-hot by the flame and produce a brilliant and steady light. The

-is made vertically adj ustable upon the screw rod, so that whenever the size of the flame is changed or adjusted the filaments can be adjusted at the same time.

By means of the construction here shown and described about three times the amount of light can be produced from the same consump tion of gas as by a burnerofthe ordinary construction. For about everg 'foot and a half of natural gas and. every twcfl et of artificial gas asixteen-eandle-power light can be produced. which is more steady, more brilliant, and which will produce atleast three ti mes as much light as an ordinary gas-burner. ments may be constructed or woven as is here shown, or in any other way that may be preferred, and the meshes must be proportioned to the size of the flame desired. This filament being heated to a white heat by the flame pro- The fila above the cylinder of regulating the size of As above stated, gas is invisible, a duced by heating the flame from the burning nd the Whole light is prothc filament to a white heat.

The flame passes both inside and outside of the filaments as it escapes from the top ofthe cylinder, and the filaments must .be made adjustable in relation to the flame according to the size of the flame desired, so as to prevent those explosions which extinguish the light.

If the parts are'no explosions occur a clai m- 1. The combination, with of a verticallyadj nectcd thereto, a

plate or disk, and
